Well then, what about the mouth. Many people would consider the mouth the filthiest area of the body. Sure there are billions of bacteria that are breeding in the oropharynx that will give a horrendous infection if it is used to bite another person. But how bad can it be if people don't mind using their mouths to kiss and lick each other, sometimes with total strangers?
If you have ever had the opportunity to observe a case in the operating room, you would know that the body part that gets the most derogatory comments for being unclean is in fact the navel. The belly button receives all sorts of derision from the nurse who has to wash it before every abdominal procedure. If it is particularly disgusting, people descend to the level of elementary school kids in their mockery of the patient's inability to maintain proper hygiene.
|Please wash this|
You say you don't have an unclean belly button because yours is an outy instead of an inny? Well you've got bigger problems because you probably have an umbilical hernia. These will eventually require a surgical repair to prevent incarceration of small bowel and an emergency operation.
So if you don't want to disgust the operating room nurse before your surgery, please remember to wash out your navel the night before you come to the hospital. The OR staff will thank you and you'll be spared the disparaging remarks that comes with neglecting your personal hygiene.
